Patent GB-228605-A (GB)
Title: An improved method of and means for controlling electric circuits
IPC: H02P7/00
Filed: 1923-11-01
Abstract: 228,605. Wilford, E. B. Nov. 1, 1923. Speed maintaining systems. - To maintain constant speed of an electric motor a fan driven by the motor blows air against a diaphragm or the like which operates a make and break device in the motor circuit so as to correct departures from a normal speed. In one apparatus for use with a small series motor, air vanes 9, revolving in a narrow chamber 10<a> produce pressure on a spring seated diaphragm 41 which actuates a counterweighted switch 42 adapted to break the motor circuit. The strength of the spring is adjusted to the required speeds, and the parts are designed to allow rapid vibration of the switch. Cooling and spark-prevention are obtained by blowing the compressed air through a hollow contact 21<a>, or by immersing the contacts in oil. Adjustment by electromagnet may replace adjustment by spring. In a modified construction one of the walls of the vane-chamber moves under air-pressure and is attached to a swivelling outlet pipe which actuates the motor circuit breaking switch. For use with shunt motors, the air compression may close a switch in the shunt circuit.

Title: Transmission method for operation condition data from peripheral equipments to a central control in a telecommunication system
IPC: H04Q3/545

Abstract: 1483001 Scanning in telecommunication systems SIEMENS-ALBIS AG 1 July 1975 [8 July 1974] 27686/75 Heading H4K In a telecommunication system including a control device ZS and peripheral equipments P1 ... Pi arranged in groups, each group being associated with a collecting point, e.g. a concentrator, T1 ... T n , data representative of the condition of each equipment is transmitted to a pre-processor TE where it is examined on a "last-look" basis, only data relating to an equipment whose condition has changed being forwarded to ZS. Each collecting point sends "condition" data relating to all its associated peripherals to a pre-processor in the form of a multi-bit message. The store of a pre-processor includes one storage block for each collecting point to which the pre-processor is connected. Within a storage block there is both an A- and a B-storage location for each equipment connected to the associated collecting point. Incoming data is written into the A-locations. Scanning of the equipments is controlled by ZS, and for each equipment the data for successive scans is compared. If a discrepancy occurs, a "change report" is written into the appropriate B-location. This report is detected by ZS, which then calls for both the new condition data and its address. The equipment whose changed condition has thereby been determined has this condition written into its A-location, while the "change report" is erased from the B-location. The points T1 ... Tn may be connected to one or more pre-processors TE via a switching network DNW. The whole system may operate in pcm TDM fashion.

Title: Improvements in or relating to oxygen supply systems
Inventor: FITT PETER WILLIAM
IPC: A62B7/06
Filed: 1959-08-14
Abstract: 938,261. Respiratory apparatus. NORMALAIR Ltd. Aug. 10, 1960 [Aug. 14, 1959], No. 27799/59. Class 81 (2). [Also in Group XXVIII] An operationally inclinable and invertible liquid oxygen converter has an external heatexchanger 80, an internal heat-exchanger 82, a differential check valve 87 and a pressureresponsive valve 50, the arrangement being such that, when the pressure in the converter is below normal working pressure, oxygen passes to a delivery conduit 88 through the external heatexchanger and the internal heat-exchanger and when the pressure is above normal working pressure oxygen by-passes the internal heatexchanger. The converter vessel comprises shells 2, 3 thermally insulated by a vacuum or closed pore cellular material between them. For filling the converter, liquid oxygen, supplied to a chamber 12 in a combined filler, build-up and vent valve 10, flows through a normally closed valve 19 and through conduits 40, 41 and an outlet 7 into the converter, displaced air leaving the converter through a second outlet 6 to atmosphere by way of a conduit 42, and chambers 13, 14, a valve 25 held open by a push-rod 24 and a tube 22 in the valve 10. On closure of the valve 25 pressure builds up in the converter through a circuit comprising the first outlet 7, the external heating coil 80, a pressure closing valve 58, the combined filler, build-up and vent valve 10 and the second outlet 6. On demand, when the pressure is below normal working pressure, oxygen flows by way of the first outlet 7, the heating coil 80 and the finned internal heat-exchanger 82 to a conduit 86, the differential check valve 87 and the delivery conduit 88, the passage of heated oxygen through the internal heat-exchanger maintaining pressure buildup. On demand, when the pressure has built up to normal working pressure, e.g. 110 lb./sq. inch, oxygen passes from the second outlet 6, through the combined filler, build-up and vent valve and through a pressure-opening valve 59 to the delivery conduit 88. The pressure opening and closing valves 58, 59 are controlled by bellows 56 and 57, respectively, and are located in the valve assembly 50 which comprises intercommunicating chambers 52, 53 connected in the build-up circuit and with the delivery conduit, respectively. In an alternative construction the converter has a removable closure member (not shown) through which all the conduits connecting the exterior and interior of the converter pass so that, for filling, the converter may be separated from the other parts of the apparatus.

Title: Data processing apparatus
IPC: G06F13/16
Filed: 1966-06-23
Abstract: 1,107,429. Data processing systems. INTERNATIONAL BUSINESS MACHINES CORPORATION. 23 June, 1966 [30 June, 1965], No. 28032/66. Heading G4A. Data processing apparatus compries a memory by pass path whereby data can be recycled through data processing circuits-without passing through the memory. Normally a pair of characters is taken from each of two memory fields in turn, so-called " secondary channel registers " holding one pair while the other is fetched, then the first characters of the two pairs are combined in arithmetic and logic circuits and the result held in a return register while the second characters of the pairs are combined, the result of the latter and that in the return register being passed on respective return channels back to the memory. Further pairs can then be processed similarly. However, when the two fields overlap and one is one character in advance of the other, the second result from the arithmetic and logic circuits is also passed direct to one of the "secondary channel registers " to save a memory access. This mode of operation is only possible if the " instruction decoder does not recognise a " special operation." The secondary channel registers" are reset just before having data gated in, by virtue of delays in set reset circuitry. The apparatus is described as a modification of that in Specification 1,070,423 but is applicable to single-character machines.
